The urban road network is a complex system that exhibits the properties of self-organization and emergence. Recent theoretical and empirical studies have mainly focused on the structural properties of the urban road networks. This research concentrates on some important parameters such as...

This paper analyses the network structure of the credit default swap (CDS) market and its determinants, using a unique dataset of bilateral notional exposures on 642 financial and sovereign reference entities. We find that the CDS network is centred around 14 major dealers, exhibits a “small...

We model a stylized banking system where banks are characterized by the amount of capital, cash reserves and their exposure to the interbank loan market as borrowers as well as lenders. A network of interbank lending is established that is used as a transmission mechanism for the failure of...

We investigate simplified models of computer data networks and examine how the introduction of additional random links influences the performance of these networks. In general, the impact of additional random links on the performance of the network strongly depends on the routing algorithm used...

The dynamics of computer networks was until recently modelled mostly with discrete-event simulations and queuing systems. Modern computer networks are becoming large and complex, and discrete-event simulation schemes are too slow to successfully model their behavior. Researchers and engineers...

This paper investigates the adaptation of cooperating strategies in an iterated prisoner's dilemma (IPD) game with individually learning agents, subject to the structure of the interaction network. In particular, we study how cooperation or defection comes to dominate the population on...

The emergence and institutionalization of cooperation in sizable groups without reciprocity receives considerable attention in game-theoretical modeling. Agents in our study play the Prisoner’s Dilemma game cooperating with tolerably similar neighbors. They may imitate cultural markers...
